Sugatsune 70-7/8" - 86-5/8" DSR701 Surface Mount Door Straightener, Silver, DSR701-2200/S-10

DSR701 Surface Mount Door Straightener For Warped Doors

DSR701 surface mount door straightener is a Sugatsune America post-production solution designed to fix warped doors by running the full height of the door, so the panel can be drawn back into plane after hanging. The silver-finish DSR701-2200/S-10 model installs on the back of the door, keeping correction hardware out of sight from the front while still accessible for adjustment. Its 70-7/8 inch to 86-5/8 inch length range covers tall passage doors within that span, giving you a single part to handle common door heights. Because it is classified as passage door hardware, it integrates into typical interior door installations where alignment matters for smooth operation. This straightener is designed specifically for door correction, so it focuses on adjustment, length range, and mounting options that support real-job alignment needs.

Door Straightener Details That Support Daily Use

• The DSR701 surface mount door straightener is installed post-production to fix warped doors, allowing correction after a door is already hung so callbacks can be handled on site without replacing the slab.
• The bar must run the complete height of the door within its 70-7/8 inch to 86-5/8 inch length range, creating continuous reinforcement that pulls the entire door into alignment rather than only spot-correcting one area.
• This straightener can be partially recessed or surface mounted to the back of the door, giving flexibility to manage clearance to walls or frames while still keeping the hardware on the concealed side.
• The silver finish provides a clean, neutral appearance on the back of the door, which matters when the rear face is visible in closets, mechanical rooms, or similar interior applications.
• The DSR701 is classified as passage door hardware, aligning it with standard interior passage door use where consistent closing and latch engagement depend on a straight, true door leaf.

Door Straightener Installation And Adjustment Use

The Sugatsune DSR701-2200/S-10 straightener can be partially recessed or surface mounted on the back of doors, so installers can choose an approach that matches the door thickness and surrounding clearances while still meeting the minimum 16 mm door thickness requirement. This door straightener provides plus or minus 10 mm adjustment from the top of the door using an M4 Allen key, which lets the installer dial in the amount of correction by tensioning the bar after the door is hung. Because adjustment is made from the top, the correction can be applied while the door remains on its hinges, supporting fine tuning during final hardware alignment. Its silver finish and defined length range between 70-7/8 inch and 86-5/8 inch support predictable layout and trimming decisions on site.

Where This Sugatsune Door Straightener Works Best

Using The DSR701 On Interior Passage Doors

This DSR701 surface mount door straightener is designed for use as passage door hardware, so it fits interior situations where warped or bowed doors interfere with smooth swinging or latch engagement. The straightener must run the complete height of the door, which means it is suited to doors between 70-7/8 inch and 86-5/8 inch in length so the bar can span from near the top edge to near the bottom. With a minimum door thickness of 16 mm, or 9/16 inch, this straightener can be applied to relatively thin doors, allowing correction on lighter interior slabs as well as standard doors within that thickness. Because it mounts on the back of the door, the front presentation of the door remains unchanged while correction happens on the concealed face. The silver finish keeps the visible hardware on the back looking consistent with other light-finish components in the opening.

Adjustment, Trimming, And Mounting For Consistent Results

The DSR701-2200/S-10 model offers plus or minus 10 mm of adjustment from the top of the door with an M4 Allen key, so installers can tension the straightener incrementally to bring a warped door back into line without over-correcting. This top-access adjustment supports quick changes after the door is swung and hardware is installed, which is useful when checking clearance to jambs and flooring. The straightener can be cut from the bottom by up to 400 mm, enabling the bar to be shortened for doors slightly under the maximum length while preserving the top adjustment mechanism. During installation, it can be partially recessed or surface mounted on the back of the door, and the manufacturer specifies M4 (U.S. #8) flathead wood countersunk screws for partially recessed mounting or wood panhead screws for surface mounting, so the fastener heads match the mounting style and seating. These installation details work together to support a repeatable, predictable method for straightening doors in the field.
